piCore 17 Beta Releases

[Juanito]

Testing beta2 on an RPi5 loading Xorg-3d, flwm, aterm, and wbar, the gui will not start without the following file:

Code: [Select]

cat /usr/local/share/X11/xorg.conf.d/99-vc4.conf
Section "OutputClass"
  Identifier "vc4"
  MatchDriver "vc4"
  Driver "modesetting"
  Option "PrimaryGPU" "true"
EndSection

I'm not sure if this is due to the changes with the frame buffer or a problem with the xorg-server startup script:

Code: [Select]

cat /usr/local/tce.installed/xorg-server
...
REVISION=$(awk -F: '/^Revision/ { print $2 }' /proc/cpuinfo | sed 's/ //g')
REVISION=${REVISION: -6}
case ${REVISION:2:1} in
    3|4) #BCM2711 and BCM2712 CPU"
        break
    ;;
    0|1|2) #BCM2835, BCM2836 and BCM2837 CPUS, all early VC4 Graphics
        cp /usr/local/share/xorg-server/files/99-vc4.conf /usr/local/share/X11/xorg.conf.d
    ;;
    *) #Unknown CPU
        break
    ;;
esac

The change was on the older pies pi3 and less.  The pi5 should not have changed.....but its something they don't make known all the time.

But I concur, that my pi5 needs it too.

I tested piCore64 17beta2 on an RPi4 - 99-vc4.conf is not needed for Xorg-3d to work.

Hi!

I just had to try piCore64 beta 2 on my faithful Raspberry Pi 4. It showed when I was loading Xorg-3d that
graphics-6.18.37-piCore-v8 was missing. I downloaded it and now Xorg-3d works and loads in a very nice manner. So RPi 4 can also use piCore64 beta 2 with Xorg-3d, It seems that a few bugs still have to be squashed in this release though.

Kind greetings,

Which bugs are you speaking of?

Hi meo

... It showed when I was loading Xorg-3d that
graphics-6.18.37-piCore-v8 was missing. ...

These are the contents of  Xorg-3d.tcz.dep:

Code: [Select]

Xorg.tcz
graphics-KERNEL.tcz
libGLES.tcz
libEGL.tczSo when you installed  Xorg-3d , it would have installed  graphics-KERNEL.
Maybe you updated the kernel but not  graphics-KERNEL?

If you run:

Code: [Select]

ls -l /etc/sysconfig/tcedir/optional/graphics-*.tczdo you see multiple versions of graphics-KERNEL?

After adding dtoverlay=vc4-kms-v3d, Xorg-3d works on an RPi3 running piCore 17beta2, so the startup script only needs modifying for an RPi5

Hi Juanito!

I can tell you exactly what I have done to make Xorg3d work also on Raspberry Pi 4. I even have done a fresh install so that I easier can find out why things happen. What I do: from the first time starting the GUI I decide what I want to have ondemand and install it as so. After that comes a funny thing that I discovered when I couldn't install Xorg-3d from the prompt. I downloaded it to my personal repo on the micro SD card. I made another try and now something happened. Packets were installed until it reached the error "graphics/6.18.37-piCore-v8 is missing". I started the GUI and downloaded the missing package *I just downloaded it". Back to the prompt typing: tce-load -i Xorg-3d.tcz and then a lot of packages were scanned and I could see an OK at everyone finalizing with Xorg-3d.tcz OK and Xorg.tcz ) OK and a green prompt. I just gave the obvious command "startx", and it did. That is the way I have it setup as a fresh install. There is a but though I get the same problem with Pragtical as before. I was thinking, could that be fixed, the Pragmatic'al' problem, by making a change in .ashrc. If there is another solution I'm all ears since I can't make Pragmatic work on a Raspberry Pi 4.

Kind greetings,
meo

PS Sometimes the screen flickers when loading Xorg-3d but it stops and gives you a prompt to start the GUI DS
